I have a tip posted here on Fixya that addresses this very problem. Here is the content from that tip:
This tip works on all Canon Imageclass 6500 series machines including the MF6500 MF6530 MF6531 MF6540 MF6550 MF6560 MF6580 MF6590 and MF6595.
First of all if you are experiencing blank copies and or prints the best thing to do is try a different toner cartridge. In rare cases the black copies/prints CAN be caused by a defective cartridge. In MOST cases it is caused by a broken or detatched laser shutter lever or arm. When a toner cartridge is inserted and the door closed, a small plastic arm opens the laser shutter. If this arm is broken or has become disconnected then the shutter is not opened. This blocks the laser from writing the copy or print image onto the drum and this results in no print being applied to the paper. If the arm is broken you CAN open the laser shutter manually and block it open. What you need to do it open the cartridge access door, remove the cartridge and look for a 1/2 inch wide slot running from left to right in the metal frame that is in the back upper section where the cartridge goes. The plastic arm that operates the black plastic shutter is on the right side. If broken you can manually lift up the shutter and "block" it open using something like a folded up scrap of paper. I know it sounds strange but I have used this repair on several of my customers machines and they have all worked fine since. If you can not find or effect the repair yourself at least you will know where to point the service person when they come out to look at it.
Good Luck and Thank You for using Fixya.

Remove and reinstall the cartridges to make sure they are properly installed. Lift the front center of the print

carriage access door to open it. Lift the door up until it locks into an open position. Press down on a print

cartridge and allow it to spring back up. Lift the cartridge out of the printer. Do the same for the other

cartridge. Slide the black cartridge into the slot on the left and the color cartridge into the slot on the right.

Press down on each one to lock it into place. Lower the print carriage access door.

I have copy and pasted this solution from another question I answered from a person with the same issue. Several people have reposnded that this solution helped them very much.
This is either your toner cartridge or more likely the plastic arm that opens the laser shutter is broken. When you insert a toner and close the access door, there is a plastic arm that opens the laser shutter. If this shutter does not open it blocks the laser and results in blank copies. If the arm is broken you CAN open the laser shutter manually and block it open. What you need to do it open the cartridge access door, remove the cartridge and look for a 1/2 inch wide slot running from left to right in the metal frame that is in the back upper section where the cartridge goes.
